SPECIFICATION forming part efl Letters Patent No. 623,176, dated Api-i11s, 1899.

Application filed October i, 1898.

To aZZ whom it may concern:

Be it known that I, EDWARD S. PARKS, residing at Danbury, in the countyof Fairfield and State of Connecticut, have invented a 5 new and usefulShoddy-Making Machine, of

which the followingis a specification.

This invention relates to a shoddy-making machine, the object being toprovide an eX- ceedingly cheap, simple, and efficient means 1o fortearing or pulling to pieces all kinds of knitted or woven fabrics,Whether of cotton, wool, or fur, and converting the same into shoddy.

Another object of the invention is to provide a machine which shall beexceedingly quick and efficient in operation, thereby overcoming theobjections to the machines now in use for these purposes.

Another object is to provide amachine in 2:; which all clogging ofmaterial is avoided.

The invention consists in providing a novel construction of feedmechanism whereby the material to be shredded or torn is fed evenly tothe tearing-disks and all danger of the maz 5 terial clogging avoided.

The invention consists also in certain details of construction andnovelties of combination, all of which will be fully describedhereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure lis a viewshowing a machine constructed in accordance with myinvention. Fig.v2 isa sectional view of the machine and operating parts. Fig. 3 is avertical section on the line 3 Seof Fig. 2. Fig. 4 is a horizontalsection on the line et 4 of Fig. 2. Fig. 5 is a detail view of the diskthrough which the material is fed.

In carrying out my invention l employ a 4o suitable base A, to which isattached a case B, within which revolve the disks C and C', said disksbeing rigidly mounted upon the shafts D and D, respectively, said shaftsbeing journaled in suitable hangers E and rotated in opposite directionsby means of the band-pulleys F, mounted upon the shafts, the outer endsof said shafts being provided with balance-wheels G, as most clearlyshown, the purpose of which is to counterbalance the 5o disks C and C,carried upon the inner1 ends of the shafts D and D, respectively.

Serial No. 692,716. (No model.)

The disk C has a ring C2 bolted to the inner face. thereof, said ringhaving the teeth C3 upon the inner face thereof, said teeth beingconstructed of steel or other suitable metal, and the ring, thoughpreferably constructed of wood, may be made of any desirable material.

The disk C has a central circular opening, and the central portion ofthe disk C4 is set 6o in some distance beyond the body of the disk C',and, in fact, the portion C/ is set in beyond the central line of thecase, as most clearly shown in Fig. 2, said central portion. beingconnected with the body portion C by means of the arms C5.

The shaft D is connected to the central portion C4, and inasmuch as thiscentral portion is connected to the disk C/ the said disk will of coursebe rotated in a direction opposite 7o to the disk C. The portion C isalso provided with a ring C2, having the teeth C3, which ring and teethare constructed and arranged exactly the same as those upon the opposingdisk.

The case B is formed with a central opening B, opposite the centralopening of the disk C', and arranged in saidA opening is aninwardly-projecting ring H, which projects inwardly nearly to thecentral line of the 8o case, and at the upper portion of the saidopening B/ isarranged the feed-hopper H', in which the material to betorn is fed, said material being drawn inward by means of the arms C:7and forced between the teeth of 85 the disks by centrifugal force.

The arms C5 clear themselves by centrifugal force of the greater portionof the material; but to prevent any possibility of the material cloggingupon the said arms I pro- 9o vide a scraper-arm I, which projectsinwardly from the ring H and engages the inner faces of the arms C5 asthey revolve about the scraper-arms, thereby clearing away any materialwhich might by any possibility remain 95 upon the said arms C5.

The central portion C4, projecting inwardly beyond the central line ofthe machine, compels all of the material fed through the hopper to beinstantly thrown between the teethroo disks by centrifugal action, andas the said.

disks are rapidly revolving in opposite directions it is clear that allof the material so thrown between them will be quickly and thoroughlytorn or shredded.

The operation of my device is exceedingly simple and is believed to beclear to every one skilled in the art to which it pertains. The shafts Dand D are revolved in opposite directions, rotating the disks C and C inopy posite directions, which disks are provided with tearing-teeth upontheir opposing faces. The material fed through the hopper H is leddirectly to the center of the machine, and

the rapid rotation of the disk C causes the material to be thrownbetween the tearingdisks by centrifugal action, and the material Aisthus quickly and easily reduced to the I claim as new, and Ydesire tosecure by Letters Patent, is-

l. In a shoddy-making machine, a pair of oppositely-rotating disksprovided with tearing-teeth upon their opposing. faces, one of saiddisks having a central opening and provided with arms for forcing thematerial be tween the tearing-disks, and a seraperarm for clearing saidarms of any accumulated mated rial, substantially as shown anddescribed.

2. In a machine of the kind described, the combination with a case, ofthe oppositely-rotating toothed disks arranged wi thin the case, one ofsaid disks having a central opening and provided with distributing-arms,the case having an opening opposite the opening of the disk and providedwith an inwardly-projecting ring, the feed-hopper and scraper-arm,together with means for rotating the disks` in opposite directions,substantially as shown `and described.
